AISI 420 Stainless Steel Spherical Powder is a martensitic stainless steel powder characterized by its high sphericity, excellent wear resistance, and high hardness after heat treatment. Its optimized particle morphology ensures superior flowability, making it ideal for advanced manufacturing techniques such as metal injection molding (MIM) and additive manufacturing processes like selective laser melting and electron beam melting. Industries benefiting from this powder include aerospace, toolmaking, and medical device manufacturing. Specific uses range from precision surgical instruments to high-strength aerospace repair coatings and durable mold components. In research, AISI 420 spherical powder is investigated for optimized atomization processes to improve powder quality, in-situ control of tempered martensite during laser cladding, and enhanced corrosion and wear resistance through tailored alloying. Its blend of performance, processability, and adaptability makes it a key enabling material in high-performance industrial production and innovation-driven scientific applications.
